Compressor wise Bambi do an economy type range, top stuff ! It works essentially on a fridge motor so is as noisy as your fridge. I think the one you'd need from them is about £370. Depends what you want to spend though ?

The advantage of having a tank or 'receiver' is when doing fine lines or shadows if you don't have a tank it pulses, this is the piston pushing the air through, so on the up stroke you get a fat line and on the down stroke you get a thin line, so I'd go for the one with a tank.
Airbrush, Iwata, they rock. No contest ! I think Jon's selling them now ? Not sure ?
